C# - AxWebBrowser control issues

We are writing a simple web browser window in C# using the AxWebBrowser control (ActiveX control accessed through Interop). The web browser window consists of a collection of AxWebBrowser controls displayed in a tab control. Each tab page contains an AxWebBrowser control. The number of tab pages is dynamic. Users can close the tab page through a toolbar button. Users can also add more tab page through a toolbar button and specify the destination URL. We have encountered two issues which we need workable and robust solutions for. ** Problems to be solved** **1.** **What we require is the ability to have different login session of the same site between different web browser tabs within the same browser window.** **2.** **What we require is a notification from the AxWebBrowser that it is being closed, so that the parent web browser window could also close the tab page that contains the control being closed.** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
